A protecting device 6 leads out the current of the series winding 31a from the transformers 51a and 52a and the current of the excitation winding 32a from the transformer 53a and synthesizes a difference current so that it be zero virtually at the time of a steady operation. An internal accident is detected from a value of this difference current. When the ratio of the difference current to a scalar sum current of the current of the series winding 31a and that of the excitation winding 32a exceeds a prescribed value, in other words, the protecting device 6 determines this as the internal accident. After the determination, a system is cut off by breakers S according to a command from the protecting device 6.

Abstract: PURPOSE:To improve the resolving power of a sensor and to improve the accuracy thereof by using AlPO4 to manufacture a flexural mode resonator to be impressed with force at both ends and rotating the resonator at a specific angle around the X-axis as a rotating axis then cutting a Z plate. CONSTITUTION:The resonator is molded of AlPO4 to a bar shaped having a width (w), length (l) and thickness (t) and both ends thereof area fixed. The external force F is exerted thereto from the outside. The oscillation frequency (f) of the fundamental wave of such bar fixed at both ends is expressed by equation I. In the equation, f0 denotes the resonance frequency when load F is not applied. From equation I, the sensitivity can be increased simply simply by increasing the length (l), decreasing the secondary ineria moment I and decreasing the Young's modulus. The resonator is manufactured by cutting the Z plate at the angle theta at which the resonator is rotated by 0--40 deg. with the X-axis as the rotating axis in order to decrease the Young's modulus E. The resonator has the max. load sensitivity and therefore the resolving power thereof is high. The sensor can be made smaller in size and resistance to impact.

Abstract: PURPOSE:To make a torque detecting mechanism simple by making a plunger freely movable into and out from the inside of the pressure chamber of an oil hydraulic circuit, and converting the pressing force of a keep plate which fixes the plunger to oil pressure. CONSTITUTION:When a prime mover 2 is operated, the revolutions of the prime mover 2 are transmitted to a driven machine 3 by means of a torque detector 10 serving also as a claw coupling. Since a keep plate 19 is mounted between the claw parts 15 and 17 of the claw coupling, the revolutions are transmitted with the plate 19. A plunger is fixed to the plate 19 and the plunger is provided in the pressure chamber filled with oil; therefore pressure is generated in oil lines 21, 23, 24 by the pressing force 19 acting upon the plate 19. The generated pressure is read with an oil pressure gage 25. Since the pressure indicated on the gage 25 is proportional to torque, the gage 25 is usable as a torque indicator.
